This enables the samples/drivers/spi_flash on quad-spi flash to run on any stm32 target with external NOR quad flash. The SPI_FLASH_MULTI_SECTOR_TEST test case is possible with quadspi too. Signed-off-by: Francois Ramu <francois.ramu@st.com>
.. _spi-nor-sample: JEDEC SPI-NOR Sample #################### Overview ******** This sample demonstrates using the flash API on a SPI NOR serial flash memory device. While trivial it is an example of direct access and allows confirmation that the flash is working and that automatic power savings is correctly implemented. Building and Running ******************** The application will build only for a target that has a :ref:`devicetree <dt-guide>` entry with ``jedec,spi-nor`` as a compatible. .. zephyr-app-commands:: :zephyr-app: samples/drivers/spi_flash :board: nrf52840dk_nrf52840 :goals: build flash :compact: Sample Output ============= .. code-block:: console *** Booting Zephyr OS build zephyr-v2.3.0-2142-gca01d2e1d748 *** JEDEC QSPI-NOR SPI flash testing ========================== Test 1: Flash erase Flash erase succeeded! Test 2: Flash write Attempting to write 4 bytes Data read matches data written. Good!
